Sr20det on e85

[lploutz23]

My set up is:
Gt2871r
1k injector
Aem map sensor
Stock fpr
255 walbro
Zeitronix flex fuel
Nismotrnic ecu

I am looking to run at 24psi on e85 and can't really find any definitive answers on if I need a different fpr or fuel pump. The most consistent info I found is that I would need either a bigger pump or run dual 255s with the stock fpr being fine. Any info would be greatly appreciated, thanks!

Are you runinning an external wastegate?

I had a similar setup as you at one time on a power-fc, 1000cc injector, 2871r but my fuel pump was a AEM 320lph the tuner said I had plenty of room for 20psi.

I think you'll need a bigger pump period.

I am running internal waste gate. Boost solenoid is hooked up to my ecu to adjust through nismotronic. I went ahead and ordered a pump. I just can't find a definitive answer about if the stock fpr would work.

It's possible that is could work on the stock frp do to the fuel pump higher output, but you have no way to your adjust fuel pressure.

I would say most members here would say get an adjustable frp and haveing a stock base pressure is ideal less you don't care about your idle.

I haven't had probs with factory fpr on pump gas...going with alternative fuel I would recommend it...at least nismo imo

Walbro 485LPH Fuel Pump
Aeromotive or AEM FPR
Cody Ace Manifold with External FPR. (otherwise you'll have so much back pressure on the exhaust side it'll eventually force the flapper open)

the ID1000's will max out around 400-450whp on ethanol. ( different dyno calibrations will argue otherwise but calculated airflow figures to match a 11.8:1 AFR put you in that ballpark)

Thanks for the recommendations. I knew I would be close to maxing out my injectors on e85, but my goal is 400-450 on e85, so I think it would be perfect.

My recommendation with headroom 80% duty is 1200cc injector, but at 90/95% duty 1000cc will work. It is unicorn blood we're talking about. Poor little 2871

Lmao, that's a lot of stress at those levels for that turbo.
DO WORK!

Yeah I will mostly be running something around 330-350hp on 93, but I want the option to push the set up there.

What's wrong with the AEM 320 e85 pump?

1000cc's with a higher base fuel pressure will net over 450whp.

That's the pump I use on mine, running base fuel pressure at 3.5 bar, 370whp no problem. It's a great fuel pump for sure! :)

Retune will be in a few months, with same pump just bigger injector (1,000) and turn up boost should net my numbers just above 400whp

What is your set up right now? How much boost are you running. I picked up an aeromotive 340 and aeromotive fpr. My dyno day is Tuesday and I am pretty excited to get this thing finished.
